Abstract

Hydroponic systems can be a solution in producing more quality and sustainable vegetables. The use
of nutrient solutions through fertigation systems is an important part of hydroponic systems. However,
many of the control of the fertigation equipment is done manually, so workers often have difficulty in
carrying out routines. The purpose of this research is to design and build an automated system on
fertigation equipment using microcontroller technology and the Internet of Things. The research
method was carried out by designing a prototype of an automated fertigation system that involves the
functional design and structural design of hardware and software for data processing. The results of
the design of the automatic fertigation prototype using ESP 32 as a microcontroller, KS0429 TDS
meter sensor, DS18B20 temperature sensor, pH 4502C sensor, JSN-SR04T sensor as water level
meter, RTC DS3231 SN as a timer, relay as an output switch, water pump as an output to increase
nutrients and water, 16x2 LCD, buzzer and button as a monitoring and control system, and Blink
software as a monitoring system through smartphones. The performance test of the tool is carried out
by means of sensor test and system test. Tests on TDS meter sensors, ultrasonic sensors, temperature
sensors, pH sensors show value of Sig. (2-tailed): 0.000 < 0.05, meaning there is a significant
correlation, and Pearson Correlation = 1, indicating a perfect correlation, and the test results of the
system with RMSE = 0.042, then the microcontroller-based and IoT-based automatic fertigation
prototype can be declared to work well.
